Description

[Detailed Description of the Invention] The present invention connects an accelerator pedal that is biased toward the engine stop position to an accelerator lever that is operated from an engine stop position to a fully open engine position across the idling position; The present invention relates to a diesel engine operating structure that is provided with a stopper that stops the pedal at an idling position against a biasing force in the direction of the engine stop position.

In the operation structure of the above diesel engine,
Conventionally, as disclosed in Japanese Utility Model Application Publication No. 56-22439, accelerator control from the idling position to the fully open engine position is performed by pedal operation, and a separate system from the pedal operation system is used. The engine stop operation system is linked to the accelerator lever, so that the engine stop can be controlled while the pedal is kept in the idling position by means of a stopper, but the structure that links the two operation systems is complicated. This also increases costs, and because the accelerator lever returns to the idling position when the engine stop operation is released, the engine automatically restarts when the engine has become hot due to long-term operation. However, there was a drawback that the engine had to be stopped for a long time.

The technical problem to be solved by this invention is that even with an extremely simple structure, the accelerator lever can be reliably held in the engine stop position, and it is extremely easy to switch between the idling position and the engine stop position. It is an object of the present invention to provide an easy operating structure for a diesel engine.

The technical means taken to solve the above technical problem is to integrally connect the pedal with an engine stop operation tool that allows the pedal to be depressed only in the direction of the engine stop position opposite to the direction in which the pedal is depressed, and to
The stopper is made of an elastic material bent in a convex shape, and in its free state, the pedal is brought into contact with the pedal to stop the pedal at the idling position, and the stopper is stopped by depressing the engine stop operating tool. releasing the operating state and switching the accelerator lever to a state in which the accelerator lever is held at the engine stop position by the pedal pressing the convex portion of the stopper and elastically deforming the stopper in this operating state; It is possible to configure it freely.

The above technical means works as follows.

A stop action state in which an engine stop operating device that allows the pedal to be depressed only in the direction opposite to the direction in which the pedal is depressed is connected to the pedal, the stopper is made of a convex elastic material, and the accelerator lever is stopped at an idling position. Since it is configured to be able to switch freely between the state where the engine is held at the stop position and the state where the engine is held at the stop position, it is possible to easily switch from the state where the engine is held at the stop position to the state where the engine is stopped by simply depressing the pedal. It can be easily switched to the opposite direction by simply stepping on the tool, and when the engine is held in the stop position,
This held state is reliably maintained by the pedal deforming the convex elastic member of the stopper.

Therefore, the present invention has the following effects. Even with an extremely simple and inexpensive structure in which the engine stop operation tool is connected to the pedal and the existing stopper is made of a convex elastic material, the accelerator lever can be reliably held in the engine stop position. It has now become possible to perform the switching operation between the idling position and the engine stop position extremely easily from either direction.

Furthermore, since the engine stop position is held by the stopper itself, the engine can be stopped quickly and reliably even if the engine has become hot due to long-term operation, making it easier to operate. It has also become possible to improve the

Next, embodiments of the present invention will be described in detail based on the drawings.

A control section 4 covered by a driving cabin 3 is disposed on the front side of a vehicle body 2 equipped with a tire-type traveling device 1, and a diesel engine 5 for driving the vehicle is mounted. A transport vehicle is constructed by providing a transport platform 6 at the rear.

A geared rail 7 extending in the front-rear direction is provided on the upper surface of the traveling vehicle body 2, and a pair of front and rear geared wheels 8, 8 that mesh with the rail 7 are provided at the bottom of the loading platform 6, and the wheels 8 on the rear side of the loading platform are provided with a geared rail 7 that engages with the rail 7. An engine 10 is connected to the engine 10 via a device 9, and a flat rail 1 extends in the front and back direction on both sides of the rail 7.

By driving the loading platform 6, the loading platform 6 can be moved toward the installation rail 14, and the tire wheels 12, 12 are brought into contact with both lateral sides of the installation rail 14, and the bottom surface of the loading platform 6 and the supporting member 13 are brought into contact with each other. By providing tension links 15, 15 between them, the loading platform 6 can be stably self-propelled along the steeply inclined installation rail 14.

A stopper 16 that comes into relative contact with the accelerator lever of the engine 10 to automatically stop the engine 10 is provided at the end of the vehicle body 2 and the installation rail 14. Also, as a matter of course, a forward/reverse switching device is provided in the travel drive system.

As shown in FIG. 4, the operating structure of the diesel engine 5 for the traveling device includes an accelerator lever 17 and an accelerator pedal 18, which are operated from an idling position to an engine stop position to a fully open engine position. Set arm 1
9 is pivotally connected by a rod 20, and a stopper 22 is provided, which stops the accelerator pedal 18 at the idling position against a spring 21 which urges the accelerator lever 17 toward the engine stop position, and also sets the limit of depression of the pedal 18. A stopper 23 is provided for changing the settings.

The stopper 22 is formed into a plate spring structure bent into a dogleg shape.
is stopped by the stopping action state A in which the pedal arm 19 contacts the pedal arm 19 in the free state, and the swinging operation of the pedal arm 19 that resists its own elastic biasing force and the biasing force of the accelerator lever 17 in the direction of the engine stop position. The accelerator lever 17 is configured to be able to be switched freely by elastic deformation to the deactivation state and a state B in which the accelerator lever 17 is held at the engine stop position in that state. An engine stop operating tool 24 for switching the engine to the stop position is integrally connected to the pedal 18, so that the pedal 18 can be used to control the accelerator from the idling position in normal driving to the engine full-open position. The stop operation of step 5 is performed by pressing the pedal 18.
By depressing the operating tool 24 directly connected to the stopper 22, the engine stop operation state is
